Why SunPatiens Are One of the Best Plants for Summer Heat
When the temperatures climb, many flowering plants begin to struggle. That’s where SunPatiens shine.
At Pam’s Greenhouses, SunPatiens are one of our favorite annuals because they deliver season-long color, thrive in both landscapes and containers, and handle Wisconsin’s summer heat better than traditional impatiens.
But even these tough plants can look a little stressed during a heat wave. If you’ve noticed your SunPatiens looking droopy lately, don’t panic. In many cases, they’re doing exactly what they’re supposed to do.
What Makes SunPatiens Different?
Unlike traditional impatiens that prefer shade, SunPatiens were bred to thrive in full sun, heat, and humidity.
They’re a great choice for:
Sunny flower beds
Foundation plantings
Patio containers
Mixed planters
Areas that receive all-day sun
Their fast growth and nonstop blooms make them a summer favorite.
Why Do SunPatiens Wilt in Hot Weather?
One of the most common questions we hear is:
“My SunPatiens are wilting. Do they need water?”
Maybe.
While wilting can be caused by dry soil, it can also happen during extreme heat. On hot afternoons, SunPatiens may lose moisture through their leaves faster than their roots can replace it, causing temporary wilting even when the soil is still moist.
If they perk back up in the evening or by the next morning, heat stress is likely the cause.
Before You Water, Check the Soil
Before reaching for the hose, check the soil.
- If the soil is dry a few inches down, it’s time to water.
- If the soil is still moist, additional watering may do more harm than good.
Overwatering can damage roots and create the same droopy appearance you’re trying to fix.
Heat Wave Care Tips
- Water Deeply When watering is needed, water thoroughly so moisture reaches the root zone.
- Water Early Morning watering helps plants prepare for the heat of the day.
- Watch Your Containers Container plantings dry out much faster than garden beds. During stretches of 90-degree weather, check them daily.
- Add Mulch Mulch helps hold moisture, keeps roots cooler, and reduces plant stress.
- Be Patient If your SunPatiens droop in the afternoon but recover by evening, they’re often just responding to the heat.
The Bottom Line
SunPatiens are among the toughest and most reliable annuals you can grow in Wisconsin. A little afternoon droop doesn’t necessarily mean something is wrong.
Check the soil, water wisely, and let these hardworking plants do what they do best: provide beautiful color all summer long.
